DigitHist: a Histogram-Based Data Summary with Tight Error Bounds

Summary: DigitHist: a histogram-based data summary for multi-dimensional selectivity with tight error bounds. Hybrid 1D/2D grids with sparse encoding and adaptive resolution; introduces u-error to minimize the gap between bounds; single-pass linear-time construction; superior precision at similar query time.
